Following is a partially completed performance report for a recent week for direct labor in the binding department of a book publisher: Original Budget..... Flexed Budget..... Actual Budget..... Variance Direct labor $ 3,410.........................................$ 4,800 The original budget is based on the expectation that 7,750 books would be bound; the standard is 25 books per hour at a pay rate of $11 per hour. During the week, 7,900 books were actually bound. Employees worked 300 hours at an actual total cost of $4,800. Required: (a) Calculate the flexed budget amount against which actual performance should be evaluated and then calculate the budget variance. (Do not round your intermediate calculations. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values. Round your answers to 2 decimal places. Omit the "$" sign in your response.) Flexed budget $3,410 Budget Variance ? b) Calculate the direct labor efficiency variance in terms of hours. (Do not round your intermediate calculations. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input the amount as positive value. Round your answer to 2 decimal places.) Direct Labor efficiency variance $ hours c) Calculate the direct labor rate variance. (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input the amount as positive value. Do not round intermediate calculations. Round your answer to 2 decimal places. Omit the "$" sign in your response.) Direct Labor Rate Variance $
